I presume the software update resets all software parameters to the same initial state as when a car leaves the factory.
For instance, from reading the VAG self study programs that most TSI engines are fitted with variable pressure/delivery oil pumps, the pressure and flow is controlled by the ecu. In the case of the 1.4 ACT tsi, its a two stage hi/lo parameter and in case of 1.0tsi (possibly 1.5tsi) pressure is fully variable and is mapped to vary with rpm and torque demand.
When coming out of the factory, oil pressure is set by default to be constant full output for the first 600 miles (1000km) to aid running in, after which it drops to the normal mapped variable output, and you should notice a step up in fuel economy.
Other variables will adapt over the same 600 mile run in period. Not really about driving style though.
It seems to me that the 600 mile period of adaptation of variables is making the kangaroo problem worse.
In my case (MY19 1.5 manual) I had the poor throttle response software update in April. It seemed to have very little kangaroo after that. Gradually over the next 600 miles the kangaroo got much worse (even in warmer weather), and now it is even worse than before the update.
On top of that it doesn't seem to have significantly improved fuel efficiency over those 600 miles.
-
For me (Manual petrol 1.5 MY19 2000 miles) it's 3 weeks with the new software and I agree with the 4 owners above -
1) The occasional dangerous lack of accel from idle revs (3-4 secs of no accel at all!) has gone.
2) Kangarooing has diminished, but still there when cold.
3) Engine runs smoother and mpg up about 5% (maybe part due to it's still running in) even though I've gone back to 95 RON.
4) Accel from <1000 revs still slow - especially noticeable in the big 2nd gear (1000 revs = 10-11mph!).
In summary - if you own a manual petrol MY19 Karoq and you have the lack of accel problem and don't want to reject the car - get the software update done ASAP. Why there's no update for older cars I don't know - perhaps the kangarooing cannot be removed by software alone?

My Karoq was built wk 50 2018 and Skoda UK are still informing me that the Q2 update/fix with regard to the 1000rpm - 1400rpm flat spot issue in 2nd gear is still not available.
The update is definitely available and working on MY19 manual petrol Karoqs.
Mine has it and so far no flat spots (mine was more pronounced below 1000rpm).
Response is still slow, but at least smooth below 1400 rpm. Some kangarooing, but no worse than our 64 1.4tsi Golf. Engine seems smoother overall, and indicated mpg slightly better, but I'll wait till next fill up to confirm.

Well so far so good, no jumping jack kangaroos or power loss/fade since the update. However only driven in urban road systems so far (would love to have had time to have got out and about) however as most of the problems are in low speed manoeuvres things are looking up. Confidence is returning in what should be/is a great SUV. Looking forward to other members comments.
Same here!
Software updated on my 1.5 manual karoq (Nov 18, MY19, post WLTP with petrol particle filter) today and the 25 mile return journey was fine - how I thought it should have driven 5 months ago!
To be honest, lack of throttle response had been improving recently with increased engine mileage and by using shell vpower petrol, and I drove back on a warm engine - so not counting any chickens yet. Kangarooing was still bad before the update, so will check it on a cold morning in the next few days.
Only downside was the 2.5 hours it took to do the update (including test drive and washing the car !!?) - bad marks for vindis cambridge.

Ask them in writing.
Something like, 'Is the update for 1.5 TSI vehicles engines / software that was supposed to be coming in the 2nd quarter now available?'.
If they do not know at Skoda / VW HQ UK then who does?
Already had a phone conversation with Skoda customer support on Friday including my conjecture.
They denied any knowledge of solutions or new engines and gave the standard 'update will be available in Q2' emphasising that might be end of June.
-
Pure conjecture on my part, but looking at recent threads on here and especially vw troc and seat ateca forums, I believe VAG may have already released a software update on new Feb 19 1.5 tsi cars. Several new owners report no problems & possibly that's why more cars are coming in !?
Can any new owners here confirm or deny this? Anyone with insider knowledge perhaps?
My worry is VAG have modified the engine in some way, suggested at by honest John and others, and older cars may not be improved.

This isn’t the bunnyhop issue suffered by several members. This is complete lack of throttle at times even when trying to move off for the first time.
The lack of throttle response is what I was talking about. Bunnyhop and throttle response are 2 separate issues, but I believe reducing bunnyhop in latest software may have created more problems with throttle response at idling revs.
-
I think this fault has been mentioned numerous times in the '1.5 sel first gear' thread. Also reported on the Seat Ateca DSG in the 'honest john' website.
My manual 1.5 has had this problem since new (now 1000 miles). It also occurs in 2nd at low speed (probably worse with manual due to a much bigger 2nd gear than the dsg).
Mine is intermittent with a cold or warm engine.
It seems to be worse on new (68 reg MY19) cars - possibly a WLTP emissions / particle filter problem?
-
Feb 2019 issue of what car reviewed a 68 plate Seat Ateca manual 1.5 EVO, and still didn't mention kangarooing or hesitancy! (although it did have a traction control system?).
Also it gave a 'true mpg' of 44.5 average - not the sort of values we're getting in normal driving. They had the cheek to assume the Karoq mpg is the same as it is 'mechanically similar' to the Seat Ateca.
Another case of 'special' review car software I think.

Hi, they do seem to be the same fault.
I think the German threads and tpi may be cars with a Gpf/ opf (Faults Oct 2018, no indication of car age).
The Italian one probably not (2017 golf).
-
I assume MY 19 manual petrol karoqs like mine with Gpf (opf) use the ECU software from 30.7.2018
It would be interesting to know if anyone without the Gpf is getting the power loss problem with a warm engine (3+ Seconds at low revs when trying to smoothly pull away).

If anyone in the UK is using Shell V power nitro+ then that iss 99 Ron minimum like Tesco momentum 99 or Costco Super unleaded. The other sellers of Super unleaded have 97RON minimum.
Sorry, I used to use the old optimax 98 RON, you're correct I used the shell V-power 99 RON. I'll try another fill, and then go back to normal 95? RON just to check if loss of power instances increase. Mpg is increasing slightly, but that may be due to engine running in still.
-
Thanks rayx, this is what I have been reading. I'm now more interested in the GPF as it seems particularly linked to my problem
(power loss not kangarooing). Moreover it seems to have improved with my latest fill of 98 RON Shell unleaded - less need for GPF regen?
My basic knowledge or GPF regen is from https://www.infineuminsight.com/articles/passenger-cars/gasoline-particulate-filters/
It occurs on decelerations or by generating a lean fuel/air mixture to increase exhaust temp. Could this be happening at idle and overriding my throttle request? A very basic control error I know, but it fits my problem.

This might explain bit more what could be the root cause of this kangaroo mystery
Used to lower NOx values as major task of valve overlap, increased production of PM particles is now managed by the GPF/OPF filter ...
taken from pre EVO engines same EA211 family
Very interesting stuff rayx!
I believe this is for all ea211 engines including the old 1.4 (which is fine on my old golf)
I can't find anything specific on the new 1.5 engine, but I agree the GPF/OPF particle filter added Sep18? is the main difference.
This is designed to occasionally 'regen' (clean?) itself at low rpm, low load - precisely the conditions where I occasionally lose power for several seconds.
Any more thoughts?
-
After second fill up, my calculated mpg is 43.1 . This was achieved with a very light foot on medium distance journeys. For comparison , my 1.4tsi golf estate (same weight as karoq) at a similar age achieved 48+. A much quieter engine as well!
-
My 1.5 manual karoq was built Oct 2018. It has minimal kangarooing when cold, but DANGEROUS intermittent loss of power (when warm) from idle in 1st and 2nd - I can't rely on it when pulling out of junctions.
Also the dsg has a much lower 2nd gear than the manual - perhaps that's why it spends less time in 1st gear? - dsg 2nd 6mph at 700rpm, manual 2nd 8mph at 700rpm.

Don't know if you’ve noticed but there is a small drain hole within the recess for the filler cap. We have a Q3 as well as the Karoq, and although the Q3 is worse, both occasionally get bunged up with dust etc, leaving quite an amount of standing water inside. I use a small bit of plastic tubing to blow the drain tube clear, then force water through the drain tube to flush it out. Might be worth a try?
Thanks for that. Mine is clear, checked the old golf and that was blocked!
I think the fold in the karoq bodywork directs more water inside, and whilst the plastic and paintwork is new the droplets stick around, especially in the ice scraper holder - I'll keep it inside the car for now.
-
I bought the karoq in November 2018, and the build quality generally seems good.
However a large amount of water gathers behind the fuel filler flap, even after a light shower.
This causes a problem when it freezes, making it difficult to open, and freezing the ice scraper to its holder - Not much use!
Has anyone else noticed this - or is my gap too large or missing a seal?
-
Hi, new member here, but have been reading this forum since buying a manual petrol karoq in November 2018.
The kangarooing doesn't seem too bad on mine, but the lack of throttle response from a warm idling engine (1st and 2nd gear) is fairly frequent and possibly dangerous fault - not a 'characteristic'.
Verified and logged by the Skoda Cambridge garage, but no response yet.
2 points I'd like to check with everyone.-
1. Was the engine management software changed for new cars around Sept 2018? (WLTP changes?) - could be reason for less kangaroo.
2. Are we sure the engine isn't running on 2 cylinders at warm idle/ anti stall? - that's what my symptoms feel like (no eco indication on my display- but I don't trust VW).
-
Hi,
Just bought a new Skoda Karoq in brilliant silver.
Hoping to get used to it soon (cars are so complicated these days even the basic SE version!)
Cheers

1.5 SEL first gear issue.

It's only the kangaroo that's worse, otherwise the April update has continued to be an improvement in throttle response. I hope there is an a update for the kangaroo in MY19 cars - I'll wait till service in November when there should be some feedback from members running the new software for more than 600 miles and then discuss it with Skoda UK.
